LOCK.

To all wzpm t may concern:

Be it known that I, REINHOLD ScHoELL of Stamford, in-the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements vin Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled 1n the art to which it appertains to make and use the same. l

' My invention relates Vto an improvement in locks designed particularly for hotels.

In hotel locks it is the practice to provide mechanisms that may be actuated by a plurality of keys such as a guest key which is adapted for one lock only; a sb-master key adapted for a series of locks, as those on one floor or corridor; and a master key for a greater number or all.

The object of this invention is to combine the devices operated by the several keys, into one mechanism thus simplifying the construction and lessening the chances of the, locklgetting out of order.

A further object is to provide a lock, which, when locked from the outside of the door by one key of the series, herein re-l ferred to as the shut-out key, cannot be un- .I locked by' any other key of the series.

AA further object is to provide a lock-having two bolts, one adapted to be actuated from the inside and the other romthe outside, with mechanism whereby the bolt that is operable :from the inside may be retracted from the outside by one of the keys of the series.

IVith these and other objects in view, my invention consists in the parts and combinations of parts as will bemore fully explained andV pointed out in the claims.

In the accompanying drawings,-- F igurel isa view in elevation of the lock, the face plate being removed and both'bolts retracted; Fig. 2 is a view in elevation ofthe face plate and the pin tumbler lock carried by the same; Fig. 3 is a view similar to Fig. 1

showing the lower or outside dead' bolt pro-- jected; Fig. 4 is a view in perspective of the cam lever; Fig. 5 is a similar view of theemergency and shut-out tumbler; Fig. v6 is a view of the lower dead bolt; Fig. 7 .is a viewv of the tumbler for the latter; Fig. 8 is a view of the lockinglever for the lower bolt; Fig. 9 is a view in section through the Specicaton of Letters atent.

main lock and also through thepin tumbler lock,.sh ow1ng the tumbler setter projected the limit by the shut out key; Figs. 10, 11 and l2 are views in section showing the several positions of the shut-out tumbler with relation to the'cam 19 and the stops 40 and 41; Fig. 13 is a view in rear end elevation of the pin tumbler lock, and Figs'. 14, 15 and 16 are views of several of the keys.

1 represents a lock casing and 2 the cover plate secured to same by screws in the usual manner. Mounted within the casing is a latch bolt 3, actuated by the roll back 4 on the knob spindle 5, which passes through the door and may be actuated by a knob at either end.

Located within the casing l adjacent the upper end thereof, is the bolt 6, which lat-Y talon 7 for the cam 8 on the hub 9 of the A thumb. turn, and is provided on its rear face with a stud 10 whichv is engaged by a shoulder 11 on the dead locking lever 12,'

to the lock casing.-

whichv is pivoted at 13 Then the bolt 6 is retracted, the stud 10 rests against the rear end of shoulder 11, j,

.and .is held against forward movement thereby, and when the bolt is projected the stud rests against the front face of the shoulder and dead locks the bolt in its locking position. The rear or freeend of lever 12 rests in the path of'movement oiV the cam' 8 on the hub 9, and whenthe latter is turned,l Y it first engages the free end of lever 12 and depresses same to release jects the latter. After the bolt 6 has been projected, the lochng lever assumes its normal position with its stud 10 `in front of shoulder 11 and locks the bolt. The Vcam 8 is kept properly centered and prevented from accidental turning by the 'spring actus ated lever-14, which .is pivoted at.13 and bears at its rear end against the cam 8. The bolt 6 is also provided with the stud 15, which lrests in elongated s lot 16 of the cam lever 17. This lever 17 is journaled on pin 18 fixed to the lock case, and is provided with affcam 19 projecting rearwardly from its hub, the said cam resting over andv in the stud10,and u lthen enters the talon in the bolt and pro`v the free ends of itsmembers 22 an contact with the free end 20 of the shut-out tumbler 21. This tumbler 21,'whieh is substantially U-shape as shown in Fig. 5, co'm-` toward the coverplate 2 of the lock by aspring 25 encircling a in 26 secured' to the casing. The other, or ljower-.end of lever 17 extends downwardly and terminates in rear of dead bolt 27, andin advance of lug 28 projecting from the rear face 'of the shank of said bolt., The lower bolt is'not operablefrom the inner side of the door, but may be actuated by any and all keys of the pin tumbler lock 29, from the outer side of the door, hence it will be seen that when bolt 27 is projected as showninFig. 3, the lug 28 on said bolt will obstruct any movement of the lever 17, and thus prevent the upper bolt 6 from being shifted to its locking position. j

Pivotally secured to the rear face of bolt 27, is the bolt dead locking tumbler 30, shown detached in Fig. 8. This tumbler is provided with ashoulder 31, which, when the bolt is in one position as shown in Fig. 1, rests against one side of the stud 32, secured to casing 1, and holds the bolt retracted, and when in its other position rests against the opposite side of said stud and holds the bolt projected. The stud 32 is secured to or integral with the lock casing, and the shoulder on the tumbler 30 is moved out of contact therewith through thev link 33, pivoted at its upper'end tothe lever 12, and at its lower end to the tumbler 30, and also moved. by the tumbler 34 carried bythe-bolt 27, the latter tumbler having an integral stud 35 which rests within the elongatedA slot 36 in thel said tumbler 30,.so that when the free v end. f said tumbler 34 is depressed by the cam 37 of the pin tumbler lock 29, the tumbler 30 will be. released from said stud 32, thus leaving the bolt 27 free to be projected by the proper key. When the lever 12 is actuated by the thumb turn at the inner side of the door, the dead locking tumbler 30 is simply rocked, without of course imparting any movement to the bolt 27.

. The tumbler 34 is pivotally mounted on a.' pin 38 carried by bolt 27 with its free end 39,l which is enlarged as shown in Fig. 7.

lresting within the talon of bolt 27, so that "when the plug of the pin tumbler lock is which wi be hereinafter explained.

turned, the caln'37 gages the free end presses the same.

ment of the tumbler moves the shoulder 31 on dead locking tumbler 30, out of the path -of stud 32, thus permitting the continued movement of the cam 37 of the pin tumbler onsaidv plug first en of tumbler'34 and deor locking position.

The bolts 6 and v'2'2' are vprovided each oril its rear ace lwith a lug engaged by a spring actuated lever 42. which tends to hold the bolts-'in ltheir Vretracted positions.

With the construction thus far jected by any key that will properly set the tumblers of the pin tumbler lock. To re vent the main bolt from being actuate' byy the guest and other minor keys, when the door has been locked from thek outside by the key herein referred to as the shut-outl This downward move- 7. 'lock 29, to Shift the bolt 27 to' its projected Y described," I i it will be seen that the bolt 27 may be pro-1 key, and also to prevent the upper or inside bolt from being actuated from the outside by any key other than a special key, hereinv referred t0 as an emergency key, I; provide the tumbler 34 with stops 40 and 41 which coact with the tumbler 21 previouslyv referred to.

When both tracted position the cam 19 on lever 17, will have pushed the tumbler 21 inwardly to a plane where the free end of' the member 23 of tumbler 21, will be intermediate the two stops 4()l and l41 on tumbler 34, thus leaving said tumbler 34 free to be moved by any key of the series, and the bolt 27 free to be projected by any of said keys. When the. per bolt 6 is projected, the turning move` uP ment of lever 17 turns the cam 19 upwardly, thus permitting the tumbler21 to rock outwardly toward the cover plate, andit is so moved by the spring 25, until the member" 23 of said tumbler rests in the path of movement of the stop 40 on tumbler 34.1 This locksthe latter tumbler against movement by vall keys except one constructed vto move the tumbler 21 to a position to release tum'- bler 34. The guests key,submaster and master keys and other minor keys will not, i

but the key herein referred to as emergency key will, as hereinafter explainedvremove the tumbler 21 to a' position between the stops 40 and 41 of the tumbler 34 and permit 'the bolt 27 to be projected.

The plug 43 of the pin tumbler lock carries the lon itudinally movable tumbler set-n terl 44. This tumbler setter 44 is secured to Athe pins 45 which `are mounted in the rearv end of the plug 43 of the pin tumbler lock;

and is normally held in its closed position,

or against the outer face of cam 37, by. the 1 springs 46 shown in dotted lines in Fig. 9.. v This tumbler setter 44 is provided with an outwardly projecting stem 47 which latter rests within the key slot in the plug 43 'of tact between the `bitting or shoulder 49and'4 the free end of` the stem 47 of the key setter 44. On the emergency key, the bitting 49 is removed from the free end a distance Vsulicient to carry the free end of member 23 of the tumbler between stops 40 and 41 of tumbler 34, when said reeend is in the planeof stop 40, as it is when the inside bolt 6 is projected as hereinbefore explained, and on the shut-out key the bitting is still closer to the free end of the key so that it will force the free end of member 23- of the tumbler to a plane beyond or to the rear of the stop 41 on tumbler. 34.

If for instance the upper or inside bolt 6 be in its projected position, and it is desired to get into the room, if the emergency key be introduced into the pin tumbler lock, its bitting 49 will first force the tumbler setter 44 rearwardly, and the latter in its rearward movement will carry tumbler member 23 from the plane of stop 40 to a position intermediate the stops 40 and 41. This frees the tumbler 34 and permits'the latter to bedepressed by the cam 37 on the pin tumbler lock as the latter -is rotated. This movement of the tumbler 34 actuates the dead locking tumbler 30 to release the same from stud 31, and a continued rotation of the cam 37 causes the latter to engage the talon of the bolt 27 and shift theV latter to its projected position. As the dead locking tumbler 30 is actuated to release bolt 27, link 33 connecting said tumactuates tumbler l2 to release bolt 6, and as bolt 27 moves to its locking position, lug 28 thereon engaging the lower end of lever 17, turns the latter in a direction to retract bolt 6. By now reversing the direction of rotation of the emergency key 47 bolt 27 will be retracted.

In order to lock the door from the outside against all other keys, the shut out key 48 is used. This key has a bitting Aso gaged that the member 23 of the tumbler 22 will be moved to the rear of stop 41 on tumbler 34, and as the bolt is projected by the key, the shouldered stud 50 on the bolt 27 moves over lip 51 on tumbler member 23, and prevents the latter from moving forwardly beyond the plane of stop 41 on the bolt on withdrawal of shut out key,

thus deadlocking the tumbler 84 against movement by any key but the shut-out key. With this construction the outside bolt may be thrown to locking position by any one of the keys, and be retracted by the key that projected it. It may also be projected by any of the keys except the 'shut out key, and.

be retracted b the emergency ke ,and may be projected y the vemergency ey and be retracted by any of the minor keys. When however the bolt vis--projected by the shutout key it isv obsolu'tely deadlocked against all other keys of the series. Again with this construction the inside bolt if projected may beretracted by vthe-emergency key but not by any of the minorfkeys. The function of the shut-out key-is principally to lock the 5 room from the outside against any and all keys, so that access may not be had to the Iroom except by the special key which is always retained at the olice.

Normally, the member 23 of the emergency and shut out tumbler .21 rests in a plane between the two sto s 40 and 41 on jfthe tumbler- 34, and there ore need not be I moved in order to project or retract the outside bolt hence in all of the minor keys the bitting should be so far removed from the free end of the key as not to engage the slide 44. When however the inside bolt is projected, the movement of the lever 17 shifts the tumbler 21 to a dead locking position,

hence in order to actuate the outside bolt,

this tumbler must be again shifted -to a position to permit tumbler 34 on the outer bolt to be actuated, and this can only be accomplished by the employment of a special Ekey having a bitting that will impart the 'necessary movement to the-slide 44. A still further movement is imparted to the tumbler 21 by the shut-out key, -so that when Ithe door has been locked by the latter no key of the series including the emergency key can project the slide 44 suciently far.

to actuate the emergency or shut-outtum- Vbler. bler with dead locking tumbler 12, of bolt 6, i

It is evident that many sli t changes invention. Hence I would have it under- ,stood that I do not wish to confine myself 'to the exact construction and arrangement of parts shown and described, but,
